Linux Support Team Lead · JetRails

I make production boring.

A decade of Linux, reliability engineering, and support leadership for high-traffic ecommerce infrastructure. I build small, sharp tools that cut alert noise, speed up triage, and let operators sleep.

Selected work

Flagship

ComfyUI-NeuralBooru

Plain English in, validated Danbooru tags out.

A ComfyUI node that turns scene descriptions into image-generation prompts using any local LLM. The model proposes tags; a 140,000-tag Danbooru whitelist validates them, so only vocabulary the image model was actually trained on survives. Zero runtime dependencies, by design.

Rust

Ferromon

Fast TUI system monitor: CPU, memory, disk, processes, services, and logs without leaving the terminal. Static builds, curl-pipe install, self-updates in place.

Rust

Ferrolog

Lightweight TUI log viewer with live search and severity filtering, TRACE through FATAL. No ambition to become Splunk.

Python · macOS

cmkview

Native macOS incident dashboard for CheckMK. Problems grouped by category, severity filters, a menu bar count, credentials in the Keychain.

Python

ClawSentry

Local-first security and ops dashboard for OpenClaw with a live SSE timeline. The activity feed shows metadata only, never message contents.

Also: a terminal aquarium where ASCII fish generate workplace drama. Deeply unnecessary. Zero regrets.

About

I have spent ten years operating Linux infrastructure that other people depend on: ecommerce platforms on Black Friday, migrations that could not lose a byte, on-call rotations that needed fewer pages, not more dashboards.

These days I lead a support engineering team and build the tooling I always wished existed: monitors, log viewers, and AI-assisted automation that does the boring parts correctly. I write my tools in Rust and Python, and yes, I use Vim.
